ANTISPREADING ATTACHMENT FOR RAILS.

Specification of Letters Patent.

Patented May a, 1915.

Application filed November 6, 1914. Serial No. 870,681.

To all whom it may concern:

Be it known that I, MARY E. SIMPSON, a citizen of the United States,residing at Yates, in the county of Kimble and State of Texas, haveinvented certain new and useful Improvements in AntispreadingAttachments for Rails, of which the following is a specification.

My invention relates to anti-spreading devices for railroad rails.

The invention aims to provide a structure of this nature especiallycomprising a span tie located between the rails and adapted to connectwith dogs, one dog being connected with each of the rails.

A second object is to provide a novel means whereby the dogs may befastened to the rails.

A third object of the invention is to provide a novel means whereby thespan ties may be connected to the dogs, and specifi cally to provide thespan tie having dove' tails at opposite ends thereof having their sidewalls inclined and the dove tails adapted to be engaged in suitablyshaped recesses in the dogs, and adapted to receive above the dogs,suitable fastening means.

Another object of the invention is to provide the means mentioned aboveof such nature that the same .may be applied to existing types of railsand while the rails are in place fastened to the usual ties.

A fifth object of the invention'is to provide a meansto secure the spantie against movement longitudinally of the rails when in place,specifically very effective means for this purpose. 4. v

With a view to attai ing the foregoing objects as well as additi nalobjects, as will become apparent from the description hereinafterfollowing taken in connection with accompanying drawings illustratingthe preferred embodiment, the invention resides in certain novelfeatures of construction, combination and arrangement of parts.

In said drawings: Figure 1 isv a top or plan view showing a portion of atrack hav-' ing my improved means applied thereto; Fig. 2 is atransverse sectionalview' on the line 22 of Fig. 1; Fig. 3 is anenlargedtransverse sectional view on the line 33 of Fig. 1; Fig. 4 is aperspective view of one of the dogs employed; Fig. 5 is a perspectiveviewof one of the span ties; Fig. 6 is a perspective view of one of thelock member retainers used to connect certain. of the parts; Fig. 7 is aperspective view of the lock memberemployed in connection with theretainer of Fig. 6; Fig. 8 is an enlarged cross sectional view on theline 88 of Fig. 1, and Fig. 9 is a. detail fragmentary perspective viewof one end of one tie connector bar.

Referring specifically to the drawings, wherein like referencecharacters designate like or similar parts, the usual railway rails, andties to which they are fastened, are shown at 1 and2 respectively. Therails 1 are shown in Fig. 1 as curved but it is to be understood thatthe invention may be practised in connection with straight rails equallyas well.

Taking up the description of my improvement, numerals3 designate dogseach com prising a flat plate 4 to engage the under surface of the railsand from which plates 4 extend riser flanges 5 from whichextendinwardly, flanges 6 to engage the upper surface of the base flange ofthe rails adjacent their outer edges. In effect by the'provision of theflanges 5 and 6, a groove is formed which receives the outer portion ofthe base flange. This base flange in the drawings is designated 17.Fastening elements 8 and 9 are provided by means of which the dogs 3 arecompletely secured to the rails.

The fastening element 8 consists of a re-' tainer having a tang plate 10below which and through the plate 3, bolts or equivalents 11 pass forthe purpose of fastening the retainer to the dog. These retainers haveriser walls or lugs 12- extending at right angles to the plate and beingprovided with apertures 13 adapted to aline in a plane transversely ofthe rails. The fastening element 9 is in the nature of a bar having anangle lug 14 at the driving end thereof. In use, to complete thefastening of the dogs to the rails, after the retainers have beensecured to the dogs and the flange 6 brought.

into engagement with the tread flanges 7 bar 9 is passed through theapertures 13 until it engages the upper surface of the tread flange ofthe rail whereupon it is driven toward the rail by a hammer or theequivalent. As the upper surfaces of these tread flanges are inclinedupwardly, bar 9 is bent by such driving action so that the corners ofthe flanges at the top of the apertures13 will bite into the bar and theparts therefore be in tight relation. Beyond the inner edge of therails, vertically exa all.

tending dove tail recesses 15 are provided,

the side walls of which are converged up wardlyat 16. Ties 17 extendthespace between opposite dogs and are fastened there to. These ties ateach end have projections 18 which are dove tail in shape and the sidesof which converge upwardly at 19. It is to be noted that the dogs andties '17 are rails and then moved upwardly with the dove tails 18passing into the dove tail recesses 15. Due to the convergence of thewalls 16 and 19, the ties 17 are limited in their upward movement toposition Where the top face of plates 3 and top faces of tie 17 will bein the same plane. After the tie is thus connected, suitable fasteningmeans is used to secure the same against downward displacement. To thisend retainers 20 exactly similar in sha e to the retainers 8 are securedto the has 17 by means of bolts 21 passing through the ties and througha base plate 22 of the retainer or fastening member. Through aliningapertures 23 in riser lugs 24 extending from the plate 22, is passed afastening member in the form of a bar 25 having a head 26 to preventdisplacement in one direction. It

will be noted from Fig. 3 that the bar 25.

projects beyond the outer faces of the lugs 24 so as to rest on theupper surface of the plates 3.

In addition to being capable of ready attachment to rails when laid, theanti-spreading \device of my invention may be readily detached andremoved from the rails when desired upon the removal of fasteningmembers 9 and 23, the detachment of ties 17 from the dogs 3 and theremoval of the dogs.

I prefer to employ means to prevent movement of the ties 17longitudinally of the rails. To this end connectin bars 28 are providedwhich fit into mortises 29 of the ties 2 and are fastened therein as byspike 30 passing through the bars 28 and ties 2. At each end, the bars28 'areprovided with projections in the form of dove tails 31 havingupwardly converging side walls 32. The ties 17 midway of their ends andon each side edge have recesses 33 of dove tail form, the side walls ofwhich converge upwardly at 34. The dove tails 31 extend into therecesses 33 and thereby connect the ties 17. -Only a single fasteningmember 30 is used to connect the bars and which fastening member is noteven essential since the bars rest on the ties 2 and the dove tails 31extend into the recesses 33. Due to the particular shape of the dovetails and recesses, the bars cannot move upwardly and owing to the factthat they rest on the ties 2, they cannot move downwardly.

It is to be understood that inasmuch as I have shown only the preferredembodiment of my invention, that changes in the details of construction,arrangement and combination of the parts may be resorted to withoutdeparting from the spirit and scope of the invention.

Having thus described my invention, what I claim is 1., In combinationwith track rails, dogs, means to removably fasten said dogs to therails, said dogs being provided with vertically-extending recesses, saidrecesses extending throughout the depth of said dogs, and meansengageable with said recesses for connecting said dogs.
